"Asymmetrically horned?" Another name for Heimdallr, according to Gylfaginning. In Gráfeldardrápa, a memorial poem on Harald Greycloak composed by the tenth-century Icelandic skald Glúmr Geirason, gold is called the "teeth of Hallinskiði." Heimdallr is also called Gullintanni, "Golden-toothed."
In the Nafnaþulur the name appears in the list of rams (hrútr).
